MapServer (formerly referred to as "UMN MapServer") is an Open Source platform for publishing spatial data and interactive mapping applications to the web. Built on C, MapServer is known for being one of the fastest mapping engines. Hundreds of vector and raster formats can be accessed in MapServer directly through GDAL.

MapServer was originally developed by the University of Minnesota (UMN) ForNet project in cooperation with NASA, and the Minnesota Department of Natural Resources (MNDNR) in 1994. The code (written in C) became open source in 1999. The MapServer project was one of founding projects of the Open Source Geospatial Foundation (OSGeo) when it started in 2006.

MapServer supports numerous OGC standards.

  • WCS Server
  • WFS Client
  • WFS Filter Encoding
  • WFS Server
  • WMC
  • WMS Client
  • WMS Server
  • WMS Time
  • SLD
  • SOS Server
